Accessories for electronic pressure switches

Mounting plate ZMP for mounting at the TOX®-Powerpackage

High pressure measuring hose ZHM

Press Force Sensor ZPS

Accessory for:

all TOX®-Powerpackages

Load capacity:

13 - 2000 kN

The press force sensor ZPS can be mounted directly on the working piston of the TOX®-Powerpackage.

It is possible to measure the press forces in push and pull direction. The sensor is sealed against dirt and moisture and should be applied with the anti-rotation device ZPSV, to avoid damage of the connection cable.

External linear position sensor ZHW

Accessory for:

Q-S, Q-K, X-S, X-K, X-AT, RZS, up to S30

The external linear position sensor provides the absolute position of the working piston in the TOX®-Powerpackage, even after power failure. Due to the external mounting on the tie rods of the TOX®-Powerpackage, the mounting position can be adapted to the conditions inside the press.

Function

All TOX®-Powerpackages line-Q, line-X and RZS are equipped with a special barrel and a magnetic ring on the working piston to detect the position of the piston.

Advantages

The linear position sensor provides non-contact sensing technology resulting in the following features:

Wear-free

Resistant to contamination

Technical data

Repeat accuracy:

± 10 μm

Supply voltage:

10 ... 30 V DC

Linear deviation:

≤ ± 0.15

Output load:

≤ 5 mA

Output voltage:

0 ... 10 V DC

Load current:

≤ 5 mA

Protection class:

IP67

When using the external linear position sensor ZHW, the effective total stroke of the TOX®-Powerpackage is to be reduced by 20 mm. The power stroke remains the same. In order to achieve the described repeat accuracy and linear deviation it is necessary to prevent the working piston of the TOX®-Powerpackage from rotating.

The ZDA displays the oil pressure in the high pressure chamber of the TOX®-Powerpackage by a 5-digit LED display. The value to be displayed is measured by the pressure sensor ZDS which is included in the scope of delivery. The ZDA is available with two digital outputs or with one digital/one analog output.

TOX®-Powerpackage Control Units

Dynamic pressure control - the defult control for all TOX®-Powerpackages

Function: During dynamic pressure control, the automatic switch from fast approach stroke to power stroke occurs every time the working piston meets resistance at any point of the stroke. The power stroke valve is connected to the return stroke chamber via the red control throttle X line and functions according to the dynamic pressure procedure. The changeover time is controlled with the control throttle X.

There are various ways to adapt and optimise the “normal” stroke of a TOX®-Powerpackage to individual requirements.

Pressure regulator in the power stroke line ZDK

Compatibility:

with ZKHZ, ZKHF, ZHO

The ZDK enables the individual adaptation of the press force.

It is applied to reduce the press force in the power stroke by guaranteeing the same level of fast approach and return stroke force.

External power stroke release ZKHF

Compatibility:

with ZDK and/or ZHO

With the ZKHF it is possible to additionally release activation of the power stroke valve by means of dynamic pressure control with an electrical signal.

Application: If the power stroke could be actuated accidentally by the control throttle X due to interference contours in the working area and shall thus be released additionally.

Stroke frequency optimization ZHO

Compatibility:

with dynamic pressure control, ZDK, ZKHZ or ZKHF

The ZHO is an optional additional assembly for improving the cycle time. The improvement during the power stroke and power stroke aeration time is approx. 20 %.

Application: In particular if the cycle time must be reduced for long power strokes.

External power stroke activation ZKHZ

Compatibility:

with ZDK and/or ZHO

The ZKHZ enables activation of the power stroke valve with an electrically actuated 3/2-way valve.

Application: Recommended for traveldependent power stroke connection or when using the TOX®-Powerpackage with upwards piston rod and high tool weight. Also usage for application related interrupted fast approach stroke.

Deactivation of the power stroke ZKHD

Compatibility:

with ZDK and/or ZHO

With the ZKHD, the power stroke can be deactivated through an electrical signal (e.g. during setup mode). It is applied, if a temporary deactivation of the power stroke is required, e.g. in setup mode.
